Definitions

  • Precast concrete column for the support of structural modular floor rectangular or quadrangular precast wide beam made of prestressed concrete for structural modular floor, and associated structure.
  • the present invention refers to a concrete precast column for the support of structural dry assembled modular floor, to a wide beam, to slab segments and to the structural framework composed of these elements, which allows simple assembling and post-tensioning procedures, limiting the logistical problems, and offering structures of noteworthy span with the possibility to compose flat and statically indeterminate floors.
  • Precast concrete structural framework systems are known that comprise some or various of the three types of basic elements that compose the system described hereafter: support columns, with or without capital; beams supported on the columns; and slab segments supported on beams or directly on the columns.
  • solutions with mortar or with elastomer are more common for the support of precast elements on elements executed on site.
  • the wide (nondropping) beams are in the opposite situation, they have less structural efficiency, but offer flat floors.
  • the lack of structural efficiency of this kind of beams in many cases can be compensated increasing the width of the beam and/or its reinforcement. In the case of prestressed beams, and even more in those having post-tensioned reinforcement, this lack of efficiency, may also be compensated by increasing the prestress load, which means increasing the amount of reinforcement.
  • Wide beams that drop under the slab are in a transition situation between the narrow (downdropping) beam and the wide (nondropping) beam.
  • the structural systems with solid slab have the limitation of a worse sitffness/weight ratio than slabs with voided sections. Despite this, the solid slabs have a significantly greater shear strength than voided sections (T sections or double T sections). That is why they are suitable for elements under significant loads.
  • the systems with T section slabs have a better stiffness/weight ratio -this is particularly true under positive moments. However, they have a quite lower performence under negative moments.
  • Post-tensioning the reinforcement offers, in general, significant advantages over the use of passive reinforcement or pretensioned reinforcement.
  • the possibility of prestressing concrete both under positive and negative flexures stands out; the possibility to erect prestressed cantilevers; and the possibility to close joints between elements which concrete has been poured in different moments.
  • using post-tensioned reinforcement in precast poses the two difficulties: on the one hand, threading the reinforcement through the several elements, which must be provided with holes or recesses properly facing each other; and on the other hand, an proper erection process must be foreseen that enables the protection of post-tensioning reinforcement to avoid its rusting must be foreseen, such as injecting the ducts or any other equivalent process.
  • Two-way floors cast in the site do not have any of the previous limitations. Despite this, precast two-way floors are somehow more limited than those cast on the site. Their bigger drawbacks are probably that they pose limitations to the free position of supports, and also to the formation irregular perimeters or irregular holes.
  • metal parts supports have two limitations: on the one hand, they lead to concentrations of efforts in the bearing points, which must be controlled to avoid local failure of concrete; and on the other hand, metal parts can not be used as joints sealing against leakage, because those are only small isolated metal parts.
  • the present invention proposes a precast concrete column for the support of a modular structure, comprising at its upper part a bearing capital for beams, having the bearing capital a square or quadrangular plan in such a way that four sides are defined to support the beams, which are characterized in the fact that each of the sides comprises concave recesses of concrete of sides parallel to the axis of the beams that define convex protrusions of concrete which sides comprise bearing surfaces such that when bearing a beam, which ends are complementary to said recesses, the bearing forces have directions contained in a plane perpendicular to the axis of the beams, having said forces a horizontal component.
  • the concave recesses are triangular or trapezoidal, and preferably in a minimum number of two on each side. Despite this, other shapes also offer good results: curved sections, sections with steps (see figure 13 ).
  • the sides of the recesses of concrete intended to support can have elastomer bands attached, to improve the contact between elements and centre the loads.
  • the four sides of the bearing capital for the beams include, in its bottom side, a protruding flap intended to contain the grout used to fill the joints between the beams and the capital of the column.
  • the present invention proposes a concrete precast column for the support of a modular structure comprising at its upper part a bearing capital for beams, having the bearing capital a square or quadrangular plan in such a way that four bearing sides are defined to support the beams, which is characterized in that each of the sides includes a rigid protruding flap attached to the bottom side of the capital and possesses rigid vertical rails attached to the vertical side of the capital that, in turn, are parallel to the axis of the beam that is supported on that side, the end side of said beam including rigid and flat plates that fit in the rails of the capital.
  • the horizontal rigid flaps will be made of fiberglass, of carbon fibre or of steel properly protected to improve its durability, and will be covered by an elastomer band in the support zone to guarantee the centring of the load.
  • the bearing capital is to be provided with embedded passing through duct segments, which allow the following threading of the post-tensioning reinforcement.
  • any of the two proposed variants allows assembling the beams in a simple and safe way, without formworks or shoring, and without the need to work with too strict tolerances of production or assembly. Additionally, both solutions allow an easy threading of the post-tensioning tendons, because they guarantee that the duct segments included in the precast elements face each other.
  • the invention also refers to a wide beam of pretensioned precast concrete of rectangular or quadrangular section for modular structure, in such a way that four sides are defined, two of them are end sides for the support on columns, which are characterized in that each of the side ends comprises convex recesses of sides parallel to the axis of the beam that comprise bearing surfaces such that, when supporting the beam over the bearing capital of a column provided with protrusions complementary to said recesses, the bearing forces have directions contained in a plane perpendicular to the axis of the beam, having said directions a horizontal component.
  • At least one of the long sides of the beam comprises concave recesses of sides parallel to the short dimension of the beams that comprise bearing surfaces such that when supporting the slab segments, which ends are complementary to said recesses, the bearing forces have directions contained in a plane perpendicular to the axis of the slab segments, having said forces a horizontal component.
  • the concave recesses are triangular or trapezoidal, and preferably in a minimum number of two on each side. Despite this, other shapes also offer good results: curved sections, sections with steps (see figure 13 ).
  • the sides of the concrete recesses intended to support can have elastomer bands attached, to improve the contact between elements and centre the loads.
  • the sides of the beam that are equipped with concave recesses include, in their bottom side, a protruding flap intended to contain the grout used in the filling of the joints between the slab segments and the beams.
  • the material of the flaps can be quite diverse (steel, aluminium, fibre reinforced mortar, fiberglass, etc.), with the sole requisites of containing the liquid mortar without suffering a deformation that will allow leakage of grout, and being anchored to the concrete mass by means of a system that will not decrease the durability of the precast element.
  • the invention also refers to a wide beam of prestressed precast concrete of rectangular or quadrangular section for modular structures, in such a way that four sides are defined, two of the end sides for the support on columns, which are characterized in the fact that each of the end sides incorporates rigid and flat plates that fit in the rigid rails, these being flat and parallel, included in the vertical side of the bearing capital of the column.
  • At least one of the long sides of the beam includes a rigid protruding flap and is attached to the bottom side of the beam, and possesses rigid and flat rails included in the vertical side of the beam that, in turn, are parallel to the axis of the slab segments that are supported on that side, the outer side of said slab segments including rigid and flat plates that fit in the rails of the beam.
  • the horizontal rigid flaps will be made of fiberglass, of carbon fibre or of steel properly protected to improve its durability, and will be covered by an elastomer band in the support zone to guarantee the centring of the load.
  • the beam will be provided with embedded passing through duct segments, which allow the subsequent threading of the post-tensioning reinforcement.
  • the main beams 15 which are characterized in that they are provided in one of their long sides of bearing edges (concave indentations, rigid flap) for slab segments.
  • the secondary beams 16 which are characterized in not having said support methods for slab segments. Despite the fact that the secondary beams do not support the slab during the assembling phase of the structure, after the tensioning of all the tendons; it is very possible that they support a significant part of the load of the slab.
  • the invention also refers to a structure composed by at least two columns, a beam and its corresponding post-tensioned reinforcement according to any of the variants of the invention.
  • the structure is completed with slab segments of prestressed precast concrete provided in their end sides with convex recesses for the the slab segments to lay on the long sides of the beams, which allow a support in the conditions described in said claim.
  • the structure is completed with slab segments of prestressed precast concrete and include in each of its end sides rigid and flat plates that fit in the rails of the beam.
  • each slab segment will be provided with embedded passing through duct segments, which allow the subsequent threading of the post-tensioning reinforcement.
  • each slab segment can incorporate in their bottom side a protruding flap intended to contain the grout that is used to fill the joints between two slab segments or between a slab segment and a beam parallel to it.
  • the material of which the grout contention flaps is made can be quite diverse (steel, aluminium, fibre reinforced mortar, fiberglass, etc.), with the sole requisites of containing the liquid grout without suffering a deformation that will allow grout leakage, and being anchored to the concrete mass by means of a system that will not decrease the durability of the element.
  • the invention uses capitals on the columns, as it is considered that the advantages provided (greater structural capacity) overcome the logistic limitations.
  • the invention does not specifically define the type of section, solid or voided, that have the elements that compose it (capital, beams and slab segments).
  • the solution that can cover a wider field of needs is the one in which the capitals are solid and the beams that are directly supported on them also are solid, whereas the slab segments are voided, preferably with double-T sections.
  • the beams, which are elements subjected to greater loads have a greater stiffness and strength with the same depth.
  • the solid section of the beams that gives a significant additional strength to shear effort, very much needed in the proximities of the supports. That is why it is also very suited for the capitals to be solid.
  • the slab segments which support a lower proportion of load, normally will not need the additional resistant capacity offered by the solid section.
  • a double-T section a significant lightening and saving of material is achieved, which only slightly decreases the strength and stiffness to flexure.
  • the voided slabs work as supported on four edges, instead of supported on four (corner) columns. This also implies a significant improvement of its deformability.
  • the invention foresees the use of big and long elements, because they mean a good compromise solution between the small segments that require formwork and the big and flat ones that pose logistic limitations.
  • the invention foresees the use of pretensioned and post-tensioned reinforcement.
  • the latter preferably two-way disposed, although without excluding the possibility that post-tensioning may only be used in one direction, according to the needs.
  • the invention does not exclude the use of other reinforcement beyond the pretensioning and the post-tensioning.
  • the elements can advantageously contain, in their interior, passive reinforcement in the shape of bars or fibres. All the reinforcings (posttensioned, restressed, passive rebars or fibres) can be made of steel or of another material commonly used to reinforce concrete, such as fiberglass, carbon fibre, aramid, or plastics suited for such function.
  • any type can be used, both regarding the type of mortar and the additives and the aggregate, lightweight or heavyweight.
  • the proposed bearing systems are halfway between the half lap support and the support with interlockings, trying to minimize the problems of both types and to maximize their virtues. They have the typical advantages of a half lap support (simple assembly) without having to choose between having a weakened section or having a single depth (flat soffit). They manage to have a section with noteworthy shear strength during the erection process besides having a single depth (flat soffit). Additionally the typical problem of the half lap supports between elements of the same depth is avoided, which is that the bottom half of the joint is very hard to fill with grouting. In the proposed invention this gets solved, and grouting the open joints and post-tensioning them restitutes the complete stiffness of the section.
  • a typical advantage of the proposed support solution with concave recesses of concrete is that the dry junction (during the erection process) between the elements is equipped with a certain stiffness to torsion in such a way that once the beam is placed over the column, the slab segments can be placed (supported) on the beam without the structure experimencing instability.
  • the total contact surface is increased, reducing the contact tension between elements. Thanks to that and to the bearing surfaces not being horizontal, the invention allows the butt joint support of the elements to keep a reasonable centring of loads without the need to use interposed materials.
  • interposed materials elastomer, mortar, resins, etc.
  • the use of interposed materials can improve the behaviour in case of significant loads or high tolerances of fabrication and assembly.
  • the joints can be grouted with compensated retraction mortar.
  • This material added to the effect of the post-tensioning, allows obtaining a structure without discontinuities of stiffness.
  • the invention refers in a general manner to a support column 1 for modular structure of precast concrete, comprising on its upper part a bearing capital 2 of beams 3, having the bearing capital 2 a square or quadrangular plan in such a way that four sides 21, 22, 23, 24 are defined that support the beams 3.
  • each of the sides 21, 22, 23, 24 comprises concave recesses 4 of sides parallel to the axis of the beams that define convex protrusions 5 which sides comprise bearing surfaces 6 such that when laying a beam 3, which ends are complementary to said recesses 4, the bearing forces have directions contained in a plane 41, 42, 43, 44 perpendicular to the axis of the beam 3, having said directions a horizontal component.
  • These concave recesses 4 can be triangular or trapezoidal, or another compatible shape, such as already described in figure 13 .
  • the four sides 21, 22, 23, 24 of support for the beams 3 comprise, in its bottom side, a protruding flap 14 intended to contain the grout of the joint between the beams and the column.
  • each of the sides 121, 122, 123, 124 includes a rigid flap 105 that protrudes and is attached to the bottom side of the capital, and possesses rigid flat rails 104 included in the vertical side of the capital that in turn are parallel to the axis of the beam 103 that is supported on that side, including the side end of said beam rigid flat plates 107 incorporated to the end of the beam that fit in the rails 104 of the capital.
  • the support capital includes passing through duct segments 11 or 111 in such a way that they allow the passage of post-tensioning tendons.
  • the invention also refers to a wide (not down-dropping) beam 3 of prestressed precast concrete for rectangular modular structure, specially conceived to be installed on the column of the invention, in such a way that four sides 31, 32, 33, 34 are defined, two of the end sides 31, 33 for the support on columns 2, which characterize in that each of the end sides 31, 33 comprises convex recesses 7 of sides parallel to the axis of the beam that comprise bearing surfaces 8 such that when bearing the beam 3 over the bearing capital 2 of a column 1 provided with protrusions 5 complementary to said recesses 7, the bearing forces have directions contained in a plane 41, 42, 43, 44 perpendicular to the axis of the beam 3, having said directions a horizontal component.
  • At least one of the long sides 32, 34 of the beam 3 comprises concave recesses 9 of sides parallel to the axis of the slab segments that comprise bearing surfaces 10 such that when bearing the slab segments 12, which ends are complementary to said recesses 9, the bearing forces have directions contained in a plane 41, 43 perpendicular to the axis of the slab segments 12, having said directions a horizontal component.
  • the invention also refers to a wide (not down-dropping) beam 103 of precast prestressed concrete for quadrangular modular structure, specially conceived to be assembled in the column of the invention 101, in such a way that four sides 131, 132, 133, 134 are defined, two of the end sides 131, 133 for the support in columns 101, which characterize in that each of the end sides 131, 133 comprises rigid flat plates 107 incorporated at the end of the beam that fit in the flat rigid rails 104 included in a the vertical side of the bearing capital 102 of the column.
